I’m looking to mod some older games, at the moment zoo tycoon 1 & 2 specifically. However they seem to be using a .bfb format for their in game data. So I can’t see what size textures I should be using, polygon count, or skeleton rigging, that I need to do, and even the stuff I already have made is useless since I can’t get the engine to accept alternate file formats correctly. I tried using .nif files but they prove to be buggy.
